SPECIFICATION forming part of Letters Patent No. 764,536, dated. July 5,1904.

Application filed June 18, 1903- Serial No. 161,977. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD J. Moons, a citizen of the United States, anda resident of Cleveland, county of Ouyahoga, and State of Ohio, haveinvented a new and useful Improvement in Bail Ear Soldering Machines. ofwhich the following is a specification, the principle of the inventionbeing herein explained and the best mode in which I have contem- IOplated applying that principle, so as to distinguish it from otherinventions.

My invention relates to devices for soldering bail-ears to the sides ofpails or cans, its object being to effect such soldering with facilityand celerity and in an economical manner.

Said invention consists of means hereinafter fully described, andparticularly set forth in the claims.

The annexed drawings and the following description set forth in detailcertain means em-- bodying the invention, such disclosed meansconstituting but one of various mechanical forms in which the principleof the invention 2 5 may be used.

In said annexed drawings, Figure I represents a side elevation of themechanism of a bail-ear-soldering device embodying my invention detachedfrom its supportingbase.

3 Fig. II represents a longitudinal central section of a portion of thedevice on the lines 2 2 of Figs. III, IV, and VII. Fig. 111 represents aplan view of such mechanism, parts being broken off and shown in dottedlines. Fig.

IV represents a horizontal section taken on the plane indicated by thelines 1 4, Figs. 1, II, V, VI, and VII, and plan view of the saidmechanism with parts removed. Fig. V represents an end elevation. Figs.V1 and V11 4 represent vertical transverse sectional views taken uponthe planes indicated by lines 6 6 and 7 7, Figs. I and III. Fig. VIIIrepresents a transverse sectional view of a portion of a can or pail,showing a bail attached thereto and partly in section. Fig. 1Xrepresents an axial section of a portion of such can or pail with theattached bail in section. Fig. X

represents a plan view of a bail-ear with a portion of abail attachedthereto. Fig. X1 represents a view similar to Fig. II, but on an en- 5larged scale and with some parts removed and representing the relativeposition of the parts when the forward end of the lever B is at itslowest position and after the cross-head D has been pulled farthest tothe right and released. Fig. XII represents a view similar to Figs. IIIand IV, but on the same scale and with the same relative positions as inFig. XI and in general of the same parts as in said Fig. XI. Fig. XIIIrepresents a view simi- 6 lar to Fig. VI, but on the same scale and ingeneral of the same parts as those of FigrXI. Upon the middle portion ofa base-plate A isbolted an upright frameA, extending transversely acrossthe plate A, as shown in Fig. 5 VII. Upon the top and in the middle ofsaid frame are supporting-ears (1/ a, which serve to guide a lever B,oscillatory in vertical planes and mounted upon a pivot-boltu., asshown. At each side of said cars a a. are secured, by 7 means ofsuitable bolts, two forwardlyprojecting plates O O, whose forwardportions 0 c are inclined downwardly from the sides of the machinetoward its middle, as shown in Figs. V and VI. Lying upon and pivoted soas tov be capable of oscillation upon and in a plane parallel with theinclined surface of each of said plates O O is a plate O, each of thelatter having secured thereto a small reservoir O for containing flux,such as muriatic acid or sal-ammoniac. From each such reservoir thereextends in a forward direction a curved feeding-tube 0, provided with acock and with a small piece of sponge c" in its extremity, such cock ands gionge regulating the dis- 8 5 charge of flux from the tube end.

Upon the under side of frame A is bolted a hanger a in \VlilClliSrigidly secured a forwardly-cxtending guiding-bar D, upon which ismounted a sliding cross-head D. This 9 crosshead is normally urgedforward by means of a spring a, secured to tl16l')LS6*1)l2l.tQ, as shownin Fig. 11. To this cross-head and upon opposite sides thereof arepivotally secured the inner ends of two links (Z (Z, whose upper endsare pivotally secured to the two treme upward position.

oscillatory plates C C and in a manner such that reciprocation of thecross-head D will effect the oscillation of the plates G C, thereservoirs C C and the feeding-tubes c c.

The oscillatory lever B is provided with a downwardly-projecting arm 7),which is provided with a pawl Z), actuated upwardly by means of a spring5 to engage a notch d, formed upon the lower surface of the crosshead D,such engagement being effected when the forward end of the lever B is inits exlever B is provided with a counterweight B, which normally holdsthe front end thereof in its elevated position, as shown in Fig. I. Suchfront end is provided with a combustion-chamber B for heating asoldering-iron B Said soldering-iron is cup-shaped to receive andembrace a bail-ear, as will be further described. Hung from the extremerear end of said lever is a connecting-rod 6 which is provided with atreadle (not shown) whereby such rear end may be elevated to depress theforward end by foot-pressure, as will be further described. Upon therear end of the base-plate are mounted two reels E, upon which are woundcoils or strips of solderingwire 0. Upon each side of the frame A aremounted two grooved feeding rolls F F, adapted to receive the said wireand when turned to feed the same forward. These rolls are provided withgears f f, meshing with each other, so as to effect the simultaneousrotation of the two rolls. lower of the two rolls and gears is effectedby means of a shaft f, upon which such lower rolls and gears aremounted, the shaft being rotated by'means of a gravity-operated pawl fmounted so as to be capable of oscillation, Fig. II, and engaging duringits rearward stroke a ratchet-wheel F, secured to the shaft. This pawlis mounted upon an oscillatory arm f hung from the shaft, and isconnected with the arm 7) by means of a link 12*. Said link may beconnected with said arm at various points by means of holes f* formedtherein, as shown and as will be readily understood, so as to vary thethrow of the arm, and hence the amount of feed effected by thefeeding-rolls.

In front of each pair of feeding-rolls and loosely mounted upon theframe A, by means of enlarged holes 9 for receiving supportingscrews a,as shown in Fig. I, is a plate G, which may be oscillated in verticalplanes, the screws (6 having their heads left a distance from the framesufficient to permit such oscillation to take place. Fixed to each saidplate Gr is an inwardly-extending arm g, Fig. VI, whose inner ends liein the rear end of the path of the arm 7) and which are normally held ina forward position by means of springs (L5 a, secured to the frame A. In

each such plate is formed an aperture g opposite the space between thetwo rolls F F,

The rear end of said Rotation of the.

into which is screwed a pipe G for guiding the solder strip from therolls to the desired point of application on the can or pail and curvedinwardly, as shown in Fig. III.

Upon the front portion of the frame A is secured a rest or cradle H forreceiving and holding the can or pail in a position such as to bring thesurface to which the ear is to be soldered in the path of thesoldering-iron B and preferably made of sheet metal bent to form a baseportion and a concave top portion, as shown. This rest is adjustabletoward and from the base-plate, so as to accommodate cans of variousdiameters-to effect their required position relatively to saidsolderingiron. Such adjustment may be effected in various ways, anadjustable rod it, secured by a set-screw it, being provided for ,thatpurpose in the machine illustrated. The rest is secured to a plate 71secured to or formed integral with the top of rod it by means ofthumb-screws 7L and bolts it" passing through a transverse slot [L5 inthe base portion of the rest, as shown in Figs. IV and V in dottedlines, whereby the rest may be adjusted transversely.

From the above-described construction it will be seen that the elevationof the rear end of the lever B effects a downward and rearward movementof the arm 6. This arm by reason of its connection with the cross-head Dthrough pawl 6 effects the rearward reciprocatory stroke of same, suchstroke being opposed by the spring (6 Simultaneously with suchreciprocation the oscillation of supporting-plates C, and hence thereservoirs C is begun, the extremities of the feeding-tubes 0 beingmoved inwardly and downwardly toward each other until they approachwithin a short distance of each other, their paths being indicated bydotted lines, Fig. V. The rest H is so adjusted that the sponges in theends of said tubes will contact a portion of the can-body in thatposition where it is required that the bail-ear shall be secured, asindicated in said figure, and apply a quantity of flux thereto. Theparts are also so arranged that such contact shall take place prior tothe time the cross-head reaches its extreme rearward limit of travel.The cross-head having retreated rearwardly some distance by the timesuch explained application of flux takes place, the downward movement ofthe arm 6 carries the pawl Z) downwardly, so as to disengage the notch(Z immediately thereafter, the spring a thereupon being allowed toreturn the cross-head to its forward position,

and so withdraw the ends of the tubes from ing source.

action being opposed by the springs a". The occupation of the extremeinward position of these pipe ends is effected simultaneously with thearrival of the soldering-iron upon the surface of the can-body. A stripof solder projecting from such ends will hence be caused to contact suchiron, be melted, and so permitted to flow to the surfaces in contactwith the lower end of said iron. Such described action during thedownward movement of the solderingiron is further accompanied by theoperation of the solder-stripfeeding mechanism as a result of thepartial rotation of the shaft f which, as will appear from the precedingdescription, rotates the feeding-rolls F F and intermittently advancesthe solder strip.

Upon reaching the can-surface the soldering-iron receives the bail-earin the cavity formed for the reception of the latter, so that such ironmay contact the required adjacent bail-ear and can-surfaces and allowmelted solder thereby to reach the same, such surfaces having beenpreviously supplied with flux. Upon releasing the treadle thesoldering-iron retracts, the parts regaining their normal positions,pawl b reengaging the notch d in the cross-head.

In order to hold the bail-ears in place prior to soldering and afterplacing upon the cansurface, a loosely or elastically mounted rod J isattached to the frame A, which projects forwardly and into the path ofthe soldering iron, the latter being provided with a notch If, Fig. V,for receiving it during the act of soldering. This rod is depressed bymeans of a spring J acting upon a plunger j, secured to its rear end,which latter is placed in the path of the lever B, as shown. This leverwhen in its normal illustrated position bears down upon such rear end toelevate the front end of the rod J. Upon the elevation of the rear leverend it will be seen that the rear end of rod J is released, allowing thespring J to act to depress the front end upon the bail-ear. Thecombustion-cham her is supplied with gas for heating the soldering-ironby a pipe 6', to which is attached a suitable flexible connection (notshown) leading from the gassupply- The front end of said rod J isprovided with a concave notch 7", Fig. III, adapted to receive aportionof the lateral surface cf a bail-ear, the latter when so receivedbeing in proper position for soldering.

1n the operation of soldering bail-ears by means of the above-describeddevice the said ears are placed upon the surface of the can body or pailafter the latter has been placed in the rest H, so as to causethe bailto abut the concave end of rod J, as shown in Figs. IX and X. Thetreadle is then operated to depressthe soldering-iron to inclose thebailear, its lower end contacting the required surfaces, such operationhaving been preceded by the application of flux to the said surfaces andthe application of solder to the iron. The rod J is meanwhile permittedto bear upon and hold the ear in place during such operation. One earhaving thus been soldered, the can is turned around so as to bring intoposition the surface diametrically opposite that to which such car hasbeen attached and the second ear attached to such diametrically oppositesurface. In order to facilitate the proper placing of the can for theapplication of such second ear, the rest H is provided with a notch It,intersecting the middle of the forward ex trcmity of its upper portion.which receives the ear first secured and then determines the position ofthe second car.
